A 280 N force is pulling an 80.0 kg refrigerator across a horizontal surface. The force acts at an angle of 18.0° above the surface. The coefficient of kinetic friction is 0.200, and the refrigerator moves a distance of 8.00 m.

  • physics -

    break up the pulling force into vertical and horizontal components.

    When determining friction force, remember the vertical component of pulling force subtracts from weigh to determine the normal force.
